Abstract

A system using a number of portable or wrist-worn remote controller units that communicate with a number of sensor units or sensor head sets for vehicle or automotive testing. An optional central communications controller can coordinate communications between the wrist-worn units and the sensor sets. A particular remote unit can associate with particular sensors or a particular sensor set and thus receive and transmit data only with that sensor set. Mechanics or technicians can run tests and take data completely from the remote units. The remote units generally contain a display screen that can show all parts and results of any vehicle test procedure. Various wireless communications techniques can be used to establish this communication.

Claims

1. A vehicle test system comprising:

a plurality of remote test units, each of said test units containing a processor, a memory, a battery, a display and a wireless transceiver;

a plurality of vehicle test sensors or test sensor sets, each of said test sensors or test sensor sets containing at least a wireless transceiver;

wherein said remote units communicate wirelessly with said sensors or sensor groups causing said sensors or sensor groups to perform vehicle tests and wherein said remote test units display data from said sensors or sensor groups;

a central communications server coordinating communications between said remote test units and said test sensors or sensor sets,

wherein at least some of said remote test units are wrist-worn;

and wherein a particular remote test unit can choose to form an association only with a particular group of sensors or test sensor sets and can release said association upon completion of a testing session.

2. The vehicle test system of claim 1 wherein said test system is a wheel alignment system.

3. The vehicle test system of claim 1 wherein said test sensor sets are alignment heads.

4. The vehicle test system of claim 1 wherein said communication is by radio.

5. The vehicle test system of claim 1 wherein a particular remote test unit is constrained to communicate only with a particular group of sensors or sensor sets.

6. The vehicle test system of claim 1 wherein a particular remote test unit can choose to communicate only with a particular group of sensors or a particular sensor set.

7. The vehicle test system of claim 6 wherein said particular remote test unit displays a particular message or icon when said particular group of sensors or particular sensor set is in use or unavailable.

8. A wireless wheel alignment system comprising:

a plurality of wrist-worn test units, each of said test units containing a processor, memory, display, battery and wireless communication module;

a plurality of sensor sets, each of said sensor sets including a wireless communication module;

a central communication server capable of wireless communication with said plurality of wrist-worn test units and with said plurality of sensor sets wherein said central communication server coordinates wireless communication between particular wrist-worn test units and particular sensor sets.

9. The wireless wheel alignment system of claim 8 wherein said display in each of said wrist-worn test units displays test data from a particular sensor set.

10. The wireless wheel alignment system of claim 8 wherein a particular wrist-worn test unit can select to communicate only with a particular sensor set.

11. The wireless wheel alignment system of claim 10 wherein said wrist-worn test unit will display a unique message or icon if said particular sensor set is in use or unavailable.

12. The wireless wheel alignment system of claim 8 wherein said wireless communication is by radio.
